Just a note to say yesterday when I switched to the latest version of SGP it had a lot of trouble finding best focus when there was light clouding and possibly dim stars.
Earlier version I found worked rather solidily - I was not sure if the solve routine simply wasn’t able to pick up the stars - and not saying hey I can’t reliably find the stars - or reporting a lot of ghosts as stars.
I was doing a few tests on the Helix nebulae NGC 7293 until light clouding came in - plus I had real issues (under another thread) with Camera cooling tool refusing to say it was in cooling mode versus warming mode - so no event plans could be triggered.
I will check my light frames for test images are correct - normally I say take 10 shots of 5 seconds each on a Williams Optics FLT 115mm scope into a ZWO ASI 071MM-c camera operating on a Moonlight DRO controller focuser - and everything goes silky smooth.
Last night was the exact opposite with this release version - focusers and cameras just didn’t want to play nice.
So I have reverted versions back to 1118 and will see if that finds star more reliably and pass that on in this thread if that is the case. Normally I get nearly perfect U curves hour after hour, night after night for teh past 6 weeks! Last night the autofocus curve looked like a earthquake curve that was overall flat - so I don’t think it detected real stars correctly!
